The implications of Monday's historic court ruling are being assessed by lawyers on both sides of the case, but already some things are clear.

On the bundling question, the court stood by the Commission's order to Microsoft to develop a version of Windows with the Media Player stripped out.

"The court makes clear that Microsoft retains the right to continue to offer the version of Windows bundled with Windows Media Player and that it is required only to make it possible for consumers to obtain the operating system without that media player, a measure which does not mean any change in Microsoft's current technical practice other than the development of that version of Windows," the court said in a statement summarizing the lengthy appeal ruling.

Meanwhile, there was little room for interpretation of the court's decision concerning the interoperability side of the case. The court agreed with the Commission's finding that "Microsoft's refusal [to share interoperability information] limits technical development to the prejudice of consumers."

Regarding the trustee, the court said the Commission was out of order granting the trustee an automatic right of access to Microsoft documents, premises and employees. It also said the Commission was wrong to make Microsoft pay all the trustee's expenses.

Microsoft was ordered to pay 80 percent of the Commission's expenses, as well as those incurred by the Commission's allies in the case, including ECIS, as well as 80 percent of its own expenses. The Commission must pick up the tab for the remaining 20 percent. Microsoft's allies, including the Association for Competitive Technologies have to foot the bill for their own legal expenses.
